BS G210 Cable for 250°C High Temperature Equipment Wiring
BS G210 cable is a high temperature equipment wire designed for fixed installations where standard PVC or silicone cables may not provide enough thermal endurance. This Intemp 250 cable uses a Class 5 flexible nickel-plated copper conductor, PFA insulation, mica tape separator and a glass fibre braided sheath with heat resistant varnish, supporting continuous conductor operation up to 250°C.
Key Features
- 250°C continuous conductor temperature: Suitable for demanding equipment wiring where sustained high heat is expected.
- PFA insulation: Provides high temperature electrical insulation with good resistance to moisture and harsh operating conditions.
- Nickel-plated copper conductor: Helps maintain reliable conductivity in high temperature environments where standard copper may be less suitable.
- Mica tape separator: Adds an additional high temperature barrier within the cable construction.
- Glass fibre braided sheath: Gives the cable extra toughness and surface protection, finished with a heat resistant varnish.
- Flexible Class 5 construction: Supports easier installation in equipment layouts where routing space is limited.

- Applications requiring moisture resistance, toughness and flexibility
- Fixed wiring where continuous conductor temperatures may reach 250°C
Installation Notes
For higher ambient temperatures, de-rating factors should be applied according to the project design. If cables are enclosed, a further de-rating factor of 0.8 should be considered. When multiple cables are grouped together and touching, grouping de-rating factors should also be applied before final cable selection.
Why Choose This High Temperature Cable
This cable is suitable for buyers who need more than a standard heat resistant wire. With nickel-plated copper, PFA insulation, mica tape and glass fibre braid, the construction is intended for demanding high temperature environments where moisture resistance, flexibility and mechanical toughness are important. We can support conductor size selection, project documentation, bulk supply and quotation requests for industrial equipment wiring.
